Q:Water shut off valve?
The water shut off valve is located where the pipe enters the house from the city water main. Maybe on the outside wall of your house near an outside faucet. Or maybe in the ground under a cover plate near an outside faucet, or maybe in the basement near where the pipe comes into the house from outside. There is also ususally a valve out at the water meter. The valve at the hot water heater just shuts of the cold water supply to the hot water heater, so it only effects the hot water.
Q:rear proportioning valve?
i got a 97 model van setting out side the shop and i went and looked at it and it doesn't have one on it,what are you calling the rear proportioning valve,it has a block that the lines split off of but not a proportioning valve,let me know if you got some kind of special edition or something,good luck.
Q:inner tube valve (Specialized) too large for the hole in rim (Bontrager)?
Yes it is possible. It sounds like you have the type of rim that takes the smaller shafted tubes and not the standard style you can normally find in departments stores. You need to take your bike to a cycle shop and have them look at the hole and see what sort of tube you need.
Q:Trumpet valves keep sticking!?
Remove the valves entirely and wipe them down with a damp cloth and clean out the valve housings of the trumpet. Then apply a generous amount of oil to the valve itself before putting it back into the instrument. If the problem persists check the valve casings for dents. If cleaning it doesn't work or there are dents, take it to a local music store and see what they can do. It shouldn't cost more than $20 unless there is a serious problem with the instrument.
Q:where are angle valves used ?
I I hope that I adequately answered your question. Wingman
Q:My second valve on my French horn is coming up slowly?
take it to a local repair shop, it probably just needs to be cleaned out.
Q:My shower handle(diverter) seems to be stripped. How shall I remove all the shower valves?
those 2 tabs are element of the cartridge. a clean cartridge comes with a disposable piece that fits in with those tabs and a sq. on the tip so which you would be able to turn and circulate it with a crescent wrench, which in turn loosens so it particularly is pulled out. possibly you ought to apply a robust needle nostril pliers to get it to tutor in case you probably did not desire to purchase the hot cylinder first. I believe utilising the plumbers grease once you're putting in the hot one.
Q:valve cover? ??????????
it keeps the oil from flying out and also keeps dirt out of your engine.
Q:Question about my bicuspid aortic valve?
so, as you already know, a typical aortic valve has three cusps. yours has two, so this is a structural issue. the point of these cusps, or leaflets, is to maintain blood flow in the appropriate direction through the heart and to the rest of the body. having a bicuspid aortic valve can be something that you inherit from one of your parents. did you have a murmur that prompted them to look for it? if your valves are young and healthy, there's probably not a problem. when it can become problematic is with age, where the leaflets can become calcified and hard, then they can not open as well (i.e. become stenotic), or not close properly (i.e. become regurgitant). if either of these two things develops, and becomes bad enough, they consider valve replacement surgery. but this is the kind of stuff that happens over years and years. you should see a cardiologist, if you haven't already been referred to one, because this is a medical condition that gets watched over time, and then if it gets bad, it gets treated. while it's not bad, it gets watched. this cardiologist will follow you over time, in addition to your regular family physician. he/she will also be keeping an eye on your aorta (the big vessel that blood enters after it goes through the aortic valve), because sometimes people who have bicuspid aortic valves also have problems with your aorta. i would also talk to your cardiologist about whether or not you need to take antibiotics in advance (i.e. prophylactically) of any dental work. i.e. because of your valve with a different shape, are you more predisposed than the average person to getting an infection there. but go to cedar point if you're young and healthy. a roller coaster should not give you any sort of problems. enjoy yourself!
